Answer:
number of ways = 120
Step-by-step explanation:
The number of ways five children can pose for a photograph line up in a row is given by the number of permutations of 5 elements in 5 different positions (positions in the line), then
number of ways = number of permutations of 5 elements = 5! = 5 * 4 * 3 * 2 * 1 = 120
Since the first children that occupies the line can be on any of the positions (5 positions) , but then the second one can choose any of the 4 remaining positions (since the first children had already occupied one) , the third can choose 3 ... and so on.
Answer:
The volume of solids is measured in cubic measurements.
Step-by-step explanation:
Examples:
Volume of a cube: V = a^3
Volume of a sphere: 4/3 x pi x r^3
Volume of a triangle: 1/2 x b x h x l
For instance, a sphere with the radius of 5 feet:
4/3 x pi x 5^3 = V
V = 523.6 cubic feet
